Abstract The abstract describing the content of the publication or report |
A selected total of 230 calibrated radiocarbon dates, chiefly from intercalated peats, are analysed from stratigraphically wellcharacterised localities in the estuarine-coastal Holocene outcrops of southern Britain (Bristol Channel-Severn Estuary (138), Southampton Water (10), Sussex coast and Romney Marsh (32), Thames Estuary-Essex marshes (26), Suffolk and East Norfolk (12), North Norfolk Barrier Coast (12). The analyses confirm the broad, tripartite lithostratigraphic subdivision of the Holocene in southern Britain, and the general similarity of the sequence to outcrops on the Atlantic and Channel coasts of France and in the Low Countries and Northwest Germany. The early Holocene sequence, dominated by silts (salt marshes, mudflats), formed when sea level was rising rapidly. The mid Holocene is characterised by intercalated silts and peats (high-intertidal to supratidal organic marshes). Sea level was rising at an intermediate underlying rate, but the rise was punctuated by several profound fluctuations (punctuations) which, moderated by local factors varying in strength from outcrop to outcrop, allowed peats/buried soils to form for periods. Silt-dominance returned in the late Holocene, at a time when sea level was rising at a low rate (excluding the last c. I 50 years). in southern Britain coastal silt (but not peat) wetlands offered resources to human communities over most of the Mesolithic, but varied in areal extent and spatial stability from outcrop to outcrop. The Neolithic period, the Bronze Age and the earliest Iron Age saw wetland resources that fluctuated between siltlands and peatlands on a time-scale of a millennium or less. The two kinds of wetland, each offering a different suite of resources, interchanged spatially at rates of the order of I -I 0 mlyr. The rapidity of change would have called for considerable resilience on the part of human groups that sought to exploit the coastal wetlands, and could have forced substantial changes in their economic basis, or led to migration or inter-group conflict. Environmental stability returned in the later Iron Age, when siltlands once again became widely available. | ||||||||||
